1.0 Project Summary:

The VA Medical Center at Central Western Massachusetts has procured a GE Discovery XR656 GII Radiographic System (XR656) to replace the aging Philips Optimus 80 DR X-Ray (80DR). This project includes designing and the site prep/modification of room 2112 to receive the new XR656.

The XR656 will be installed into Room 2112 by GE engineers upon completion of the site prep work by the Contractor as required by this SOW and in accordance with the GE Health Care Site Planning Pre Install Manual and drawings. The GE references are available for download from http://www3.gehealthcare.com/en/Support/Site_Planning.

The 80DR will remain operational during construction and the installation and commissioning of the XR656. Upon completion of the in XR656 installation by GE Engineers the Contractor shall finish the outstanding work for this room.

Once the XR656 is operational, GE Engineers will decommission and remove the 80DR from room 2108. After removal of the 80DR the Contractor shall prepare room 2108 to receive a yet to be procured Fluoroscope. The Contractor shall prepare the electrical and HVAC loads to receive a notionally selected SIEMENS LUMINOS AGILE MAX or equal Fluoroscopy System. Additionally the design shall prepare the walls, celling, lighting, and doors for this space, as required and remove and install flooring.

This Contract also includes converting rooms 2110 (change room) and 2108 (staff bathroom) into a common control room to serve both 2112 and 2108 rooms. Room 2108A (patient bathroom) shall be modified to serve both rooms with a doors to both rooms and a means to provide access to the room by one patient at a time. The existing layout is shown by figure 1 below as a reference.
